JOSEPH RUMBAUGH, OF FREMONT, OHIO.

IMPROVEMENT IN REFRIGERATOR-BUILDINGS.

Specification forming part of Letters Patent No. 206,140, dated July 16, 1878 application filed February 11, 1878.

To all 'whom it may concern:

Be it known that I, J OSEPH RUMBAUGH, of Fremont, in the county of Sandusky, and in the State of Ohio, have invented certain new and useful Improvements in Ice-Houses; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of an ice-house, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertaius to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a vertical section of my ice-house, and Fig. 2 is a horizontal section of the same.

A represents the foundation of the ice-house, upon which is the floor B, said floor being made double and the space filled with cinders or other suitable non-conducting packing. Upon the floor B are two sets of walls, 0 and D, forming a flue, a, between them, as shown. The top is also made of two parts, E and F, the part E forming a junction with the inner walls (1 O, and the part F with the outer walls I).

A vertical partition, G, divides the chamber thus inclosed into an ice-chamber, H, and a cooling-chamber, I. Between the two partsE and F of the top or ceiling is a continuation of the flue a, or, in other words, a continuous;

unbroken space is left all around and on top of the inner frame 0 E.

All the walls O D, ceiling E F, and partition G are constructed in the same manner as the floor B-that is to say, each part is made double, and the space between packed with suitable non-conducting filling.

J is the roof, also made double and packed with a ventilator, K, in the center at the top, said roof forming a chamber, L, above the ceiling E F. Surrounding the entire ice-house, roof, and all is a casing, M, forming an airspace, b, all around and above the ice-house, said airspace being open at the bottom.

On the sides of the ice-chamber H are racks N to form flues to allow the cold air to descend in said chamber.

0 O are the entrances to the ice and cooling chambers, respectively.

At the bottom of the partition G is a series of passages, d, leading from the ice-chamber to the cooling-chamber. Similar passages d are made near the top of said partition.

6 c are slides in the cooling-room over the passages 01 d, as shown.

f are passages from the bottom of the icechamber into the flue or space a.

From the cooling-chamber I are passages h at the bottom into the flue or space a and at the top thereof are passages i into the outside flue or space 11.

In the top of the coolin g-chamber is aventi lator, P, leading into the chamber L, and on top of said ventilator P is avalve, R, operated from the inside of the cooling-chamber to allow hot air to escape.

The cold air from the ice-chamber passes through d into the cooling-chamber, and also, at f, into the flue a. In this latter flue the cold air will entirely surround the inner walls and then pass at it into the cooling-chamber.

At d the hotter air will pass from the cooling-chamber into the ice-chamber, and at i into the flue 1), formed by the outer casing M. Through this outer flue there is a constant current of air, which serves to draw off the vitiated and hot air.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In an ice-house, an ice and a cooling chamber, constructed with two sets of double walls, with continuous air-flue between them, a double roof with ventilator, an exterior casing open at bottom, forming a continuous fine around the entire ice-house, and passages 01, d, f, h, and t, substantially as shown and described, and for the purposes herein set forth.

In testimony that I claim the foregoing I hate hereunto set my hand and seal this 12th day of January, 1878.

JOSEPH RUMBAUGH. [L. s.]
